Unit 1: Evaluate Summative

Species B out competes Species A for resources, causing the decline in Species A’s population.

Both Species A and Species B benefit equally from unlimited resources, leading to population stability.

Species A preys on Species B, causing Species B’s population to stabilize at a lower level.

Species A experiences resource limitations that reduce its population, allowing Species B to stabilize.

Both the deer and wolf populations increase due to better resource availability.

The wolf population increases immediately after deforestation, leading to a decline in the deer population.

The deer population declines sharply due to reduced food availability, leading to a delayed decline in the wolf population.

Both the deer and wolf populations remain stable despite deforestation, indicating they are not impacted by resource changes.

Native grass species out competed invasive plants despite the changing environmental conditions.

The ecosystem's stability was unaffected by the drought, as invasive plants did not impact native grasses.

The prolonged drought created conditions that favored invasive plant species, leading to a shift in the ecosystem's structure.

Both native grass and invasive plant populations remained constant, indicating resilience to environmental changes.
